WICHITA, Kansas — A convicted sex offender has spent the last 13-years in the Kansas Sexual Predator Treatment program, but he was able to find a way to upload pornographic pictures to his social media accounts.

Prosecutors say it’s a crime he has already pleaded guilty to.

Kansas authorities have seen this face far too many times.

Mark Brull, 38 is a convicted sex offender and his track record dates back to 1997 when he served prison time for indecent solicitation of a 13-year-old.

Brull has spent many years at the Larned State Hospital in the Sexual Predator Treatment program, but that hasn’t stopped him from committing another sex crime.

“We want to think that when someone goes to prison that people are going to be safe and obviously in this particular situation he found a way to victimized someone again,” said Kathy Williams, Executive Director for Wichita Area Sexual Assault Center.

Court records show Brull had a friend helping him from outside.

The convicted sex offender gave Ryan Dancosse, 40 of Wichita passwords to his social media profiles.

Prosecutors say with Brull’s knowledge and agreement, Dancosse would find and copy images of pornography then upload the images to accounts on Facebook and Twitter.

The inappropriate photos were shared with a 14-year-old boy in Massachusetts.

The boy was able to view these images on his computer and then discussed them with Brull.

We learned the conversation took place in 2011 sometime between April 29th and May 9th when Brull communicated with him through email and telephone.

State officials believe Brull may have smuggled a contraband cellphone into the facility.

“Having the abilities to access all of that social media and use it in a way to hurt someone is not generally something people think off,” said Williams.

The Executive Director of the Wichita Area Sexual Assault Center Kathy Williams says it’s frustrating to hear that someone can commit such a crime while under watchful eye.

She argues the attention now needs to focus on helping the victim.

“We need to believe and support them and seek counseling for them if they’re ready to do that or wait until they’re ready to talk about this and to fully process this,” said Williams.

Brull’s sentencing date is scheduled for October 4th and he could spend up to 10 years in federal prison.

Dancosse also pleaded guilty to one count of receiving child pornography. His sentencing date is scheduled for October 2nd.
